    Background: Bronchial asthma is a chronic inflammatory disorder of the airways associated with airway hyperresponsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in the early morning.Methods: This study has recruited 25 newly (male/female) cases of Bronchial Asthma diagnosed on the basis of spirometry in the Department of Pulmonary Medicine, Era’s Lucknow Medical College & Hospital (ELMC&H). Patients were received Fluticasone/Formoterol (200/10 μg OD). The drugs were administered through metered-dose inhaler (MDI).Results: The mean forced expiratory volume recorded before treatment 54.92±4.47 in a group who were treated with formoterol/fluticasone combination changed to 75.48±5.03 after the treatment. No significant adverse effect of this regimens was observed.Conclusions: The results of this study revealed this regimen showed a significant improvement in lung functions without any significant adverse event

    A vinculin tail hotspot mutation in cancer patients affects mouse embryonic fibroblast motility

    Vinculin, an essential adhesion scaffolding protein, physically links membrane bound integrin and cadherin receptors to filamentous actin. Cells that fail to express vinculin or possess dysfunctional vinculin exhibit rounded morphology, enhanced motility, and resistance to apoptosis and anoikis. Therefore, vinculin is classified as a tumor suppressor protein in which mutations have serious consequences in cancer. A possible ‘hotspot’ region—an encoded region of a protein that is highly inclined to mutate and phenotypically manifest—has been identified at in the tail-domain of vinculin at residue R925. At this residue, a specific histidine mutation has been linked to several types of cancer. The purpose of this study was to examine the possibility of residue R925 as a hotspot region and test whether the R925H mutation in vinculin enhances motility properties in a model cell line. To examine the status of R925 as a hotspot region, we mined several databases to link certain prevalent mutations in vinculin to different types of cancer. R925H was the most prominent mutation in vinculin that was present in 5 types of cancer, confirming R925 as a hotspot region. In order to assess whether R925H affected the motility of mouse embryonic fibroblasts (MEFs), actin binding and bundling activity of mutant vinculin was compared to that of wild-type vinculin. We found that R925H mutant vinculin had lower actin bundling ability. To evaluate the changes in motility patterns caused by the introduction of R925H, we conducted random motility assays to measure the two-dimensional migration of MEFs on micro-fabricated and microfluidic devices. Mutant MEFs on hydrogels displayed significant differences in motility compared to wild-type cells—particularly in total accumulated distance, persistence and velocity. However, further investigation is required to interpret these findings. The insight on the effects of the R925H mutation on cell motility will serve as one of the first steps to unravel the complexities of vinculin’s potential role in several human cancer settings.Bachelor of Scienc

    Comprehensive Summary of Performance-Affecting Factors of CCDS

    Get PDF
    This paper considers four factors affecting the functioning of a surface channel CCD. The factors considered are: the interface states, feed forward due to barrier modulation, surface potential fluctuations, and the avalanche multiplication in a CCD. A computer program has also been developed to analyze the performance of a CCD

    Impacted Canine: Diagnosis and Prevention

    Get PDF
    Since impacted canines are encountered often, with an incidence rate of 1 to 2% in the general population, it is important for a dentist to identify the signs and symptoms of this condition and follow interceptive treatment or orthodontic treatment. Features of buccal or palatal canine impaction show lack of canine bulges in the buccal sulcus and asymmetry in dental midlines. Diagnosis of impacted canines at an early age of 8 to 10 years can reduce further complications, such as surgical exposure or root resorption of the lateral incisors, and will reduce the total duration of the treatment. The interceptive orthodontic treatment procedure with extraction of the primary maxillary cuspids can prevent impaction of the permanent maxillary cuspids and additional sequelae

    Model-based motion estimation for synthetic animations

    Full text link
    One approach to performing motion estimation on syn-thetic animations is to treat them as video sequences and use standard image-based motion estimation meth-ods. Alternatively, we can take advantage of informa-tion used in rendering the animation to guide the motion estimation algorithm. This information includes the 3D movements of the objects in the scene and the projec-tion transformations from 3D world space into screen space. In this paper we examine how to use this high level object motion information to perform fast, accu-rate block-based motion estimation for synthetic anima-tions. The optical ow eld is a 2D vector eld describ-ing the translational motion of each pixel from frame to frame. Our motion estimation algorithm rst com-putes the optical ow eld, based on the object motion information. We then combine the per-pixel motion in-formation for a block of pixels to create a single 2D projective matrix that best encodes the motion of all the pixels in the block. The entries of the 2D matrix are determined using a least squares formulation. Our algo-rithms are more accurate and much faster in algorithmic complexity than many image-based motion estimation algorithms.

    Integrated analysis of circulating cell free nucleic acids for cancer genotyping and immune phenotyping of tumor microenvironment

    The circulating cell-free nucleic acids (ccfNAs) consist of a heterogenous cocktail of both single (ssNA) and double-stranded (dsNA) nucleic acids. These ccfNAs are secreted into the blood circulation by both healthy and malignant cells via various mechanisms including apoptosis, necrosis, and active secretion. The major source of ccfNAs are the cells of hematopoietic system under healthy conditions. These ccfNAs include fragmented circulating cell free DNA (ccfDNA), coding or messenger RNA (mRNA), long non-coding RNA (lncRNA), microRNA (miRNA), and mitochondrial DNA/RNA (mtDNA and mtRNA), that serve as prospective biomarkers in assessment of various clinical conditions. For, e.g., free fetal DNA and RNA migrate into the maternal plasma, whereas circulating tumor DNA (ctDNA) has clinical relevance in diagnostic, prognostic, therapeutic targeting, and disease progression monitoring to improve precision medicine in cancer. The epigenetic modifications of ccfDNA as well as circulating cell-free RNA (ccfRNA) such as miRNA and lncRNA show disease-related variations and hold potential as epigenetic biomarkers. The messenger RNA present in the circulation or the circulating cell free mRNA (ccf-mRNA) and long non-coding RNA (ccf-lncRNA) have gradually become substantial in liquid biopsy by acting as effective biomarkers to assess various aspects of disease diagnosis and prognosis. Conversely, the simultaneous characterization of coding and non-coding RNAs in human biofluids still poses a significant hurdle. Moreover, a comprehensive assessment of ccfRNA that may reflect the tumor microenvironment is being explored. In this review, we focus on the novel approaches for exploring ccfDNA and ccfRNAs, specifically ccf-mRNA as biomarkers in clinical diagnosis and prognosis of cancer. Integrating the detection of circulating tumor DNA (ctDNA) for cancer genotyping in conjunction with ccfRNA both quantitatively and qualitatively, may potentially hold immense promise towards precision medicine. The current challenges and future directions in deciphering the complexity of cancer networks based on the dynamic state of ccfNAs will be discussed
